Sorry about my triplicate post below. I've got NO idea how that happened.
The annual pass ($125 today) gets your car in the gate without paying the
(today) $10/car fee.
There's an annual boat pass sticker ($75 today) that gets your boat in the
gate without paying the (today, IIRC) $5 boat fee. The sticker goes on
your annual pass. Note that kayaks don't have to pay the boat fee.
The dive reservation ($10 today) covers the reservation and does not
apply (today) to walk-ins.
Today, on a weekday, you could probably walk in with your dive gear and
kayak, and go yak diving, and pay nothing. And I'd consider you
completely nuts. MMM, I wonder if they charge for pack mules? ;-)
Do the math. The annual pass is (today) 12.5 car entries. There are a fair number
of folks that do that. The boat pass is (today) 15 boat entries. There aren't very
many of those. I've been told that Phil Sammet and I have the only boat
passes. The last two years running, they've had trouble figuring out how
much to charge me. Fortunately, last year, Ranger Chuck wrote the price
on the envelope with the stickers, and this year it only took a few minutes
to sort out the price. Last year it took the better part of a day.
